  DESCRIPTION OF EMBODIMENTS Embodiments of a printed matter sampling apparatus according to the present invention will be described below with reference to FIGS. In addition, the same code | symbol was attached | subjected to the same component through the whole figure.

  The printed product sampling apparatus 1 receives at least a printed product row conveyed in a stacked manner from an upstream (left side in the drawing) conveyor (not shown) and continuously conveys the printed product row, and at least so as to widen the interval between the printed product rows. A momentary stopper 3 that sandwiches and stops a single printed product from both sides, and a guide spatula 4 that advances between the expanded printed product rows and guides the printed product that continues between the rows in the extraction direction from the conveyor. It has the extraction conveyor 5 which receives and conveys the printed material guided by the guide spatula 4, and the two trays 6a and 6b which receive the printed material conveyed by the extraction conveyor 5.

  The conveyor 2 includes a driving roller 2a, driven rollers 2b, 2c, and 2d, a plurality of string-like endless belts 2e wound around these rollers in parallel (one is shown in the figure), a roll bar. (Not shown) and the like.

  The instantaneous stopper 3 includes a cylinder 3a disposed opposite to both sides of the printing unit to be conveyed, and a plate-like pressing piece 3b fixed to the tip of the piston rod of the cylinder 3a. The instantaneous stopper 3 has a configuration in which the printed material is sandwiched from above and below at a gap position in the row interval of the string-like endless belt constituting the transport conveyor 2. Therefore, the instantaneous stopper 3 is not in contact with the transport conveyor 2 when the printed material is being sandwiched, and the transport conveyor 2 can continue to be driven. A plurality of the instantaneous stoppers 3 are arranged at a predetermined interval back and forth in the conveyance direction of the printed matter, and are arranged at three locations in the illustrated example.

  A guide spatula 4 is disposed downstream of the instantaneous stopper 3. The guide spatula 4 is arranged in an inclined manner with respect to the printed product row, and is advanced obliquely downward toward the upstream side and obliquely upward toward the downstream side by a drive source 4a (see FIG. 3) such as a linear actuator. Can retreat. Therefore, when the guide spatula 4 advances, the printed material transported on the transport conveyor 2 rides on the guide spatula 4 and is guided in a guide direction that faces downstream and obliquely upward.

  On the guide spatula 4, the 1st detection part 7 which detects the front-end | tip of the printed matter guided by the guide spatula 4 is arrange | positioned (refer FIG. 2). For the first detection unit 7, for example, an optical non-contact detector such as a photoelectric switch can be used.

  A nip roller 8 (see FIG. 2) is disposed immediately downstream of the first detector 7. One of the nip rollers 8 is a driving roller, and the other is a driven roller. The nip roller 8 can convey the printed material at a higher speed than the conveyance speed of the conveyance conveyor 2. The nip roller 8 is supported by a support (not shown) fixed to the frame of the printed material sampling apparatus main body. In FIG. 2, reference numeral 9 is a guide plate fixed coaxially with one of the nip rollers 8, so that the printed material is not pinched up and is sandwiched between the nip rollers 8.

  The sampling conveyor 5 has a sliding base 5b on which the printed material slides on a fulcrum 5a, and a plurality of endless belts 5c arranged in parallel passing through the lower surface while being placed on the upper surface of the sliding base 5b. (Refer to FIG. 3) and a driving roller 5d and a driven roller (not shown), which are wound around an endless belt 5c and supported by a slide base 5b. Oscillation is driven between an inclined position indicated by a solid line in FIG. 1 and a horizontal position indicated by an imaginary line.

  In the illustrated example, the trays 6a and 6b for receiving the extracted printed matter are arranged at the front and rear positions of the extraction conveyor 5, and the tray 6b arranged on the downstream side (rear side) of the extraction conveyor 4 has a disordered arrangement. The tray 6a is a tray that accepts the printed material that has been extracted because it is generated, and the tray 6a that is arranged on the upstream side of the sampling conveyor 4 is a tray that receives the printed material that has been extracted for inspection.

  By setting the swinging angle of the sampling conveyor 5 to the inclined position (solid line position in FIG. 1), the printed material can be discharged to the tray 6b, and the swinging angle of the sampling conveyor 5 is set to the horizontal position (virtual position in FIG. 1). By setting the line position), the printed material can be discharged to the tray 6a. However, when discharging the printed matter to the tray 6a, the extraction conveyor 5 is swung to the horizontal position while the printed matter extracted at the inclined position is held on the extraction conveyor 5, and the endless belt 5a of the extraction conveyor 5 is rotated in the extraction direction. And the operation of discharging to the tray 6a is performed.

  On the extraction conveyor 5, there is provided a pressing roller 10 that holds the printed material in cooperation with the extraction conveyor 5. The pressing roller 10 is a follower type that does not include a drive source, and an elastic member such as a coil spring (not shown) is provided at an appropriate location, thereby applying a desired pressing force to the printed material conveyed on the sampling conveyor 5. It is preferable to do.

  The position of the pressing roller 10 is a position where the distance to the nip roller 8 is substantially the same as or slightly larger than the total length of one printed product, that is, a position where one printed product can be accommodated between the nip roller 8 and the pressing roller 10. Has been placed.

  A second detector 11 is further provided on the upstream side of the instantaneous stopper 3 to detect the positional deviation of the printed material by detecting both sides of the printed material conveyed on the conveyor 2.

  As shown in FIG. 4, a conveyor 21 with a rejecter including a reject unit 20 is disposed on the downstream side of the printed material sampling apparatus 1. The reject unit 20 is configured by an oscillating conveyor. When the reject unit 20 is opened, the printed material conveyed on the conveyance conveyor 2 of the printed material sampling apparatus 1 falls from the end of the conveyance conveyor 2. The case where the paper is discharged from the reject unit 20 is a case where the waste paper is discharged. For example, a case where a plurality of members are continuously discharged by predicting a joint of a printing paper roll, or a pattern generated continuously in the printing press. In some cases, a deviation or the like is detected in the printing machine and discharged.

  Below the end position of the conveyor 2, a basket 12 for receiving the printed matter that falls is provided. The basket 12 is supported so as to be able to move forward and backward between a pulling position for receiving printed matter falling from the end of the conveyor 2 and a pulling position for pulling down the conveyor 2, and is driven forward and backward by a linear actuator 13. can do.

  The basket 12 includes an inclined bottom 12a that is inclined rearward and downward from the vicinity near the end position of the conveyor 2 and a rear wall 12b that rises from the rear end of the inclined bottom 12a. The inclination angle of the inclined bottom 12a is designed in accordance with the angle when the printed material falls.

  The printed matter sampling apparatus having the above configuration operates as follows.

  Printed matter discharged from a printing press, a rotary press, or the like is continuously conveyed in a row on an upstream conveyance conveyor (not shown). The transported conveyor 2 of the printed product sampling apparatus continuously transports the printed product row while maintaining the same transport speed and the same shearing state.

  In this embodiment, the printed matter is conveyed on the conveyor 2 at a speed of 40 (m / min). Moreover, in this embodiment, the conveyance speed of the nip roller 8 is 240 (m / min), and the conveyance speed of the extraction conveyor 5 is 120 (m / min). The extraction conveyor 5 usually has a conveyance speed that is two to three times the conveyance speed of the conveyance conveyor 2.

  A single-leaf extraction function for extracting a single printed material for inspection from the continuously conveyed printed material row will be described. When the operator inputs a single leaf sampling signal, the following operations (1-1) to (1-9) are performed.

  (1-1) The instantaneous stopper 3 is actuated and, as shown in FIG. 5, the row interval 31 of the printed matter rows is widened by sandwiching the rows of the printed matter 30. Although not appearing in the figure, the three instantaneous stoppers 3 are operated at predetermined time intervals (for example, 0.2 to 1 second) in order from the downstream side.

  (1-2) As shown in FIG. 6, the guide spatula is driven to advance at the row interval widened by the instantaneous stopper 3.

  (1-3) As shown in FIG. 7, the pressing pieces 3b of the three pairs of instantaneous stoppers 3 are simultaneously retracted, and the stopped state of the printed matter example is released. When the stopped state of the printed material row is released, the printed material row flows out and the printed material 30a rides on the guide spatula 4.

  (1-4) As shown in FIG. 8, when the first detection unit 7 detects that one printed product 30 a has run on the guide spatula 4, the guide spatula 4 moves backward and the subsequent second printed product 30 b. The central instantaneous stopper 3 of the three instantaneous stoppers 3 is operated so as to sandwich the subsequent printed material 30b of the printed material 30a on the guide spatula 4 and temporarily stop. The printed product 30a detected by the first detection unit 7 is conveyed at high speed by the nip roller 8 (FIG. 9).

  (1-5) The printed material is continuously conveyed on the conveyor 2 again by the instantaneous stopper 3 that has temporarily stopped the printed material releasing the stop.

  (1-6) The printed matter that has passed through the nip roller 8 in the above (4) is discharged to the extraction conveyor 5. The conveyance speed of the extraction conveyor 5 is set to be slower than the conveyance speed of the nip roller 8. Thus, by making the conveyance speed of the extraction conveyor 5 slower than the conveyance speed of the nip roller 8, the printed material is braked so that the printed material discharged from the nip roller 8 does not rise.

  (1-7) The printed material conveyed on the extraction conveyor 5 comes out of the nip roller 8 and then is pressed onto the extraction conveyor 5 by the pressing roller 10. The conveyance rotation of the extraction conveyor 5 is stopped while being sandwiched between the pressing rollers 10.

  (1-8) With the printed matter held on the extraction conveyor 5, the extraction conveyor 5 is driven to swing until it reaches a horizontal position.

  (1-9) When the extraction conveyor 5 is in the horizontal position, the conveyor belt of the extraction conveyor 5 is reversely rotated, and the printed matter is discharged to the tray 6a. Thereafter, the extraction conveyor 5 is driven to swing and returns to the inclined position.

  The time from (1-1) to (1-5) is about 2 seconds, and the time from (1-1) to (1-9) is about 8 seconds. Therefore, inspection inspection can be performed six times per minute.

  Next, a description will be given of a positional displacement printed material extraction function for extracting a printed material that has undergone positional displacement when a positional displacement occurs on an upstream printing press, a rotary press, or the like or on a conveyance line.

  The second detection unit 11 that detects the positional deviation of the printed material is disposed at a position that detects both sides of the printed material that is conveyed on the conveyor on the upstream side of the instantaneous stopper 3. The second detection unit 11 can employ an optical non-contact detector similar to the first detection unit 7. When the misalignment occurs in the conveyed printed material, any of the second detection units 11 arranged at the positions on both sides of the printed material generates a detection signal. When the detection signal is received, the second detection unit 11 operates in the following order. .

  (2-1) Based on the detection signal from the first detection unit 11, first, the instantaneous stopper 3 operates in order from the downstream side for a predetermined time interval (for example, 0.2 to 1 second), and temporarily prints a part of the printed matter in the printed matter row. Stop and widen the line spacing of the printed lines.

  (2-2) The guide spatula 4 advances in the row interval of the printed material example spread by the instantaneous stopper 3.

  (2-3) The pressing pieces 3b of the three instantaneous stoppers 3 are simultaneously moved backward to release the stop of the printed material, and the printed material is conveyed again.

  (2-4) The conveyed printed material runs on the guide spatula 4 and is discharged to the extraction conveyor 5 at a high speed by the nip roller 8, is conveyed on the extraction conveyor 5, is discharged to the tray 6 b, and is stored therein.

  (2-5) When the printed matter detected by the second detection unit 11 rides on the guide spatula 4 and is detected by the first detection unit 7, the guide spatula 4 moves backward as shown in FIG. Of the three instantaneous stoppers 3, the central instantaneous stopper 3 is activated to stop the subsequent printed material on the printed material on the guide spatula 4. In order to identify and detect the printed matter detected by the second detection unit 11 in the first detection unit 7, the distance between the second detection unit 11 and the first detection unit 7, the moving distance of the transport conveyor 2, the first detection It can be identified from the respective detection times of the unit 7 and the second detection unit 11.

  (2-6) While the subsequent printed material is stopped, the printed material that has run on the guide spatula 4 is conveyed at high speed by the nip roller 8 and delivered to the sampling conveyor 5.

  (2-7) When the printed material sandwiched between the nip rollers 8 is separated from the subsequent printed material, the pressing piece of the central instantaneous stopper 3 is moved backward to release the stop of the printed material, and again in the normal conveying state Return to.

  Next, the waste paper discharge function will be described with reference to FIGS. The generation signal of the waste paper is generated from a printing press or a rotary press.

  When the control unit (not shown) of the conveyor 21 with the rejecter receives the waste paper generation signal, the control unit generates the loss paper, the distance from the loss paper generation point to the reject unit 20, the conveyance speed of the waste paper, and the like. Then, the time required for the waste paper to reach the reject unit 20 is calculated, and the reject unit 20 is tilted to the imaginary line position in FIG. 1 to form a pit in the transport path of the printed matter.

  The basket 12 is driven to advance in accordance with the timing at which the controller 20 tilts the reject unit 20 and accepts the waste paper that falls from the conveyor 2.

  The basket 12 has an inclined bottom 12a and a rear wall 12b, and the printed matter falling in the basket 12 is stacked in the order of dropping. This produces the following advantageous effects:

  An example of damaged paper is a seam of printing paper rolls. Before the printing paper roll is carried into the printing press, the end of the printing roll to be connected is connected by an adhesive device called a paster. This seam position is generally detected by an optical sensor which is a seam sensor in the printing press. After passing through the joint sensor, the joined printing roll is cut into a predetermined length and conveyed on a conveyor. Therefore, when the seam detected by the seam sensor reaches the rejecting part 20 is calculated in advance, and the information is given to the control part of the conveyor 21 with the rejecting. When discharging such a spoiled paper from the reject section 20, it is difficult to accurately discharge only the spoiled paper with a seam. Discharge in multiple copies. Since the length of one roll paper is determined and the seam position is also determined, for example, 40 sheets are discharged at the beginning of conveyance, and the opening operation time of the reject unit 20 is gradually limited by experience values. Thus, the operation of gradually reducing the number of discharges, for example, discharging 10 copies, is performed. In such an operation, the position of the damaged paper in the discharged printed matter, that is, the number of the damaged paper is important information. Therefore, if the printed matter falling in the basket 12 is stacked in the order of dropping, the information can be obtained.

  The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention.

  For example, in the above-described embodiment, an example in which the fulcrum 5a is the swing center and the tray is arranged before and after the sampling conveyor 5 is shown. However, the swing center of the sampling conveyor is set at the end on the guide spatula side (for example, the roller 5d). It is also possible to have a configuration in which a plurality of trays are arranged behind the sampling conveyor.

  In the above embodiment, an example in which there are three pairs of instantaneous stoppers is shown, but two pairs or four or more pairs may be used.
